Now it doesn't say Page not found because the second page I added I made it a static page and a posts page. So now you can click all you want on the Home page but nothing happens. Is there a way to get the Home (orginal Index page) back again so I can edit it?

I don't believe you can actually modify or delete the Home tab; in the MistyLook theme, it's always a link to the URL of your blog. It's not a "page" that you can edit. It should show your most recent posts (unless you've changed the options under Settings > Reading?). So far as I am aware, the default "original page" is an initial post. You should be able to just write a post, publish it, and have it show up on the first page.

When you add another top-level page to your blog, MistyLook will add another tab for that page.
